configure fails if no argp.h is found. On musl, it is standard practice to use argp-standalone since the C implementation does not provide it like with glibc. Reproducible: Always
This is almost exactly the same as bug 477290
I've just tried to reproduce this (with latest stable which is 1.16.3), and the thing appears to work. ebuildtester --atom media-libs/libv4l --portage-dir /home/j/work/foss/gentoo/gentoo --profile default/linux/amd64/17.0/musl (I patched ebuildtester to work on arbitrary profile). Am I missing anything?
it seems so: checking for ALSA... yes checking for libudev... yes checking whether x86_64-gentoo-linux-musl-gcc is Clang... no checking whether pthreads work with -pthread... yes checking for joinable pthread attribute... PTHREAD_CREATE_JOINABLE checking whether more special flags are required for pthreads... no checking for PTHREAD_PRIO_INHERIT... yes checking for library containing dlopen... none required checking argp.h usability... no checking argp.h presence... no checking for argp.h... no configure: error: Cannot continue: argp.h not found the bug could be mitigated by adding sys-libs/argp-standalone in case of elibc_musl (it's libv4l-1.16.3 here)

Hope the commit pushed on Jun 5 helped. Postponing virtual/argp idea for now - can always be done when we run out of more tangible problems, the current situation doesn't seem too painful to me.
